DESCRIPTION OF THE INVENTION

[0002] The present invention relates generally to a “Shoe structure provided with interchangeable vamps”, especially to a shoe structure provided with interchangeable combinations and styles of vamps.

[0003] According to the previous techniques, the connected portion between a shoe board and a vamp of general shoes including sandals, sports shoes or cotton shoes, etc. are usually sealed so that one is not able to make any changes of styles and patterns. The present invention has already gained the U.S. Pat. No. 6,418,643 named “Shoes structure provided with interchangeable accessories.” (hereafter called forgoing invention). Please refer to FIG. 1, the features of that forgoing invention are: inside the shoe board 1 there are a plurality of receiving spaces 1 a which are set up with a plurality of separation pieces 2 and on the edges of certain vamps 3 there is a retaining piece 4, which can be buckled and fixed into the separation pieces 2 so as to connect the shoe board 1 and the vamp 3. And a shoe pad 5 is set up on the shoe board 1.Another shoe pad 6 is set up in the combined construction in accommodation with the shoe pad 5 so as to fix it on the shoe pad 5. By means of the techniques of the above forgoing invention, though different styles of vamp 3 can individually connect with the shoe board 1, there are still regrets in practical that the scopes of the application are not wide enough. Now stated the details as follows:

[0004] The feature of above foregoing invention can only be suitable for structure of sandals but totally not for shoes such as sports shoes, leather shoes, and informal footwear that have “totally wrapped vamp”. Therefore, the vamps of the shoes on sales now that have structure of wrapped vamp such as informal footwear and cotton shoes, etc. are not interchangeable. Besides, the most often broken portion of general shoes like informal footwear and sports shoes is at the front of a shoe between the shoe board and the vamp. After being used for a certain time, it will break because of losing functions of sticking and stitching, generally called “mouth opened” which needs improving.

[0005] Thus, the primary objective of the present invention is to provide a “shoes structure with interchangeable vamp” that has been researched and developed, improved object to the said structure of the approved patent. Primarily set up with a push piece, covering board and a buckling board between the shoe board and the front of the vamp. The push piece and the covering board are set up in the inner side of the shoe board and primarily set up with a plurality of fixing board pillar at each side rib with a plurality of long holes on the board Surface of the cover board. The buckling board is set at the bottom portion of the vamp. Its back rib is set with a plurality of square-shape buckling base. By means of the buckling base set up into the long holes, the fixing board pillar on the push piece can be pushed and fixed with buckling base so as to be exactly combined the wrapped-type vamp with the shoe board.

[0006] Another object of the present invention is to provide a plurality of buckling bases at both edges behind the board and at the backside behind the vamp provided with square-shape piece to be buckled with the buckling base, on which there are ribs and on the square-shape piece there are rib piece. With the combination between the square-shape piece and buckling base, the combination between the vamp and the shoe board will thus become more intensive and fixed.

[0007] Please refer to FIG. 2 to FIG. 6, the present invention “shoes structure with interchangeable vamp” comprises a shoe board 10, a shoe pad 20 and a vamp 30, primarily provided with a fixing buckling device 40 between the shoe board 10 and the vamp 30 and a plurality of supplemental fixing buckling base 50, which enables the shoe board 10 and the vamp 30 to be disassembled and combined randomly as well as to make its combination more fixed, which comprises: the shoe board 10 is a shoe-shape base, on which there are a plurality of fixing hole 11 and its inner side is provided with partial components to set up with a fixing buckling device 40 and supplemental fixing buckling base 50.

[0008] The shoe pad 20 is a smaller shoe shape relative to the shoe board. On its proper back edge is provided with a plurality of fixing pillar 21, which can be fix into the fixing hole 11 on the shoe board 10 to fix the shoe pad 20 on the upper of the shoe board 10, and in order to replace and take the shoe pad 20, is provided with a strap 22 at the proper backside of the shoe pad 20.

[0009] The vamp 30 is a shoe shape wrapped at its side edge. At the proper bottom portion is provided with partial fixing function between the fixing buckling device 40 and supplemental fixing buckling base 50.

[0010] The fixing buckling device 40 comprises a put-in base 41, a push piece 42, a covering board 43 and a buckling board 44:

[0011] The put-in base 41 is a tub piece shape provided at the front of the inner side of shoe board 10 and on its proper portion is provided with a defining piece 411 used for the fixing of the push piece 41.

[0012] The push piece 42 is in a long square shape. On its proper portion is provided with a hollow part 421 fixed with the defining piece 411 so as the make the push piece 42 slip into the put-in base 41. And each side edge around it is provided with a plurality of the fixing board pillar 422 in an irregular order.

[0013] The covering board 43 covers on the push piece 42 in a relative shape to the put-in base 41. At the portion that the board faces the fixing board pillar 42 is provided with a plurality of long hole 431.

[0014] The buckling board 44 is fixed at the proper bottom portion of the vamp 30. At each long hole 431 at the back board facing the covering board 43 is provided with a plurality of square-shape buckling base 441, which center portion is hollow and the outer portion is sealed just to insert the long hole 431.

[0015] The supplemental fixing buckling embodiment 50 comprises a buckling base 51 and a square-shape buckling board 52. At both side and the back of the shoe board 10 is provided with a buckling base 51 in a shoe shape, which proper inner side is provided with a buckling-g piece 511 and formed a rib on that buckling piece 512. The square-shape buckling board 52 is fixed in the central and back portion of the vamp 30, on which inner side is provided with a rib piece 521, which can be exactly buckled and fixed with the rib 512 while the square-shape buckling board 52 is buckled in the buckling base 51.

[0016] By means of the above said components' combination, not only one can combine and disassemble the vamp 30 such as informal footwear, cotton shoes, etc. which is in a wrapped shape with the shoe board 10, but also can enhance the strength of the combination and make it more convenient to be assembled.

[0017] Please further refer to FIG. 7 and FIG. 8, the technical assembling and applicable means of the present invention are: when each components of the fixing buckling device 40 and the supplemental fixing buckling embodiment 50 are provided at the pre-fixing position of the vamp 30 with the shoe board 10, place the buckling set 441 on the vamp 30 into the long hole 431 of the board 43 and then push the push piece 42 to let the fixing board pillar 422 of the push piece 42 to fix into the hollow part of the buckling set 441 and set across the buckling set 441 to let go the long hole 431. Thus, one can accomplish the front combination of the shoe board 10 and the vamp 30. The set the square-shape buckling board 52 of the vamp 30 into the buckling base to be buckled so as to complete a closely combination of the central and back portion between the shoe board 10 and the vamp 30. In the final, insert the shoe pad 20 onto the shoe board 10 of the vamp 30.

[0018] As shown in FIG. 6, when the square-shape buckling board 52 is buckled in the buckling base 51, it is a type of buckling and fixing with buckling piece 511 and is the rib 512 on the bucking piece 511 and shows a combination structure of being wedged and stuck up with the rib piece 521 of the buckling board 52. In this way, it will become more fixed and denser. Besides, it will become more convenient and taster to assemble and disassemble the vamp 30 and the shoe board 10.

[0019] On the contrary, when disassembling and replacing the vamp 30, first pull the strap 22 on the shoe pad 20 and take out the shoe pad 20. Then, depart the square-shape buckling board 52 from the buckling base 51. The fixing buckling device 40 allows the push piece 42 pushed in an opposite direction so that the buckling set 441 will depart from the long hole 431. Thus, it will also depart the vamp 30 and the shoe board. There is one thing needed to explain further, when the square-shape buckling board 52 depart from the buckling base 51,one only needs to pull and twist a little so as to achieve the purpose of disassembling vamp 30 in a convenient and fast way.

[0020] Furthermore, as shown from FIG. 9 to FIG. 14, the major feature of the present invention is structure of interchangeable styles of wrapped style of vamp 30. Thus, those vamps which are total wrapped (as shown in FIG. 9 and FIG. 10) or half wrapped (as shown from FIG. 11 to FIG. 14) are applicable to the structure of the present invention so the users can have changeable choices in wearing footwear. And with the a shoe board 10 accompanies a variety of colors and styles of vamp 30 which enable the users to choose freely and lead to an increasing sales from which the manufacturers can then gain more sales.

[0021] In addition, in the respect of the practical examples of the present invention, the buckling base 51 of the supplemental fixing buckling embodiment 50 can be applied on a board base in an arrangement of a shoe pattern, or can be applied on wherever on the shoe board 10 in an individual or pair type, or further applied on the covering board 43 of the fixing buckling device 40 to collocate a sandal's vamp 30 assemble. Please refer to FIG. 3 and FIG. 15 and FIG. 16, at the proper both sides of the covering board 43 of the fixing buckling device 40 can be provided with the buckling base 51. Thus, when user wishes to change the vamp 30 of sandal's style, one can directly buckle the square-shape board on the vamp 30 into proper buckling base 51 and then put the shoe pad 20 on the shoe board 10, By way of this, user can change the wrapped type shoe into a sandal. FIG. 15 and FIG. 16 show when the fixing buckling device 40 has not buckled on the shoe board 10, the shoe board 10 can still be provided with sandal style's vamp 30 buckling which are more changeable and practical in applications. Of course, the quantity and position of the square-shape buckling board 52 can be adjusted in a best way according to the patterns and styles of the vamp 30.

[0022] In conclusion, the present invention “Shoe structure provided with interchangeable vamps” is indeed a design with both practical and progressive features which totally conform to the important conditions of patent application. Herein apply for and hope it will be examined and approved soon.
